2.3 Attentions when using the Touch Screen 1. When using it please remember not to tear the screen surface with any sharp object. 2. In order not to affect the normal use of the touch screen, please keep its surface clean and dry, and ensure that your fingers are clean and dry. 3. In order not to affect the precision of positioning on the touch screen, please avoid handling or touching the glass frame of the touch screen by your hands when you are carrying out touching operations. 4. To ensure the safety of users, please clean the screen and frame with a soft cotton cloth after turning the screen off. In order to prevent the remaining water mark from affecting the touch operations, do not wipe it with a damp rag. 5. Do not place or drop anything which could obstruct it in the four corners of the screen or any part of its frame, because this could separate the screen from the frame and stop the screen from being able to sense position properly. Please avoid leaving water and dust in the gap between the casing and glass when you are cleaning the frame. 6. Avoid using it in dusty environments, or in very hot or humid conditions. The abrupt change of environmental temprature may in a short time cause on the glass screen inner surface some tiny spray, which will disappear after some time and will not affect the normal use. Note: When it is used in normal operation, the touch screen process will not affect the running of other computer processes. User Guide 23
